I made a library to detect tables and extract to markdown or csv. It uses a new table recognition model I trained.

Announcing Surya OCR 2! It uses a new architecture and improves on v1 in every way:

- OCR with automatic language detection for 93 languages (no more specifying languages!)
- More accurate on old/noisy documents
- 20% faster
- Basic English handwriting support





Find Surya here - .

Surya OCR 2 is more accurate across all document types. It also compares favorably to Tesseract and Google Cloud OCR. The benchmarking script is in the repo.

Language is not hinted to Surya 2 for these benchmarks. github.com/VikParuchuri/s…

I just released new surya layout and text detection models:

- 30% faster on GPU, 4x faster on CPU, 12x faster on MPS
- Accuracy very slightly better
- When I merge this into marker, it will be 15% faster on GPU, 3x on CPU, 7x on MPS I used a modified version of efficientvit from MIT - - which was then adapted by @wightmanr . I made some small modifications, including adding a segmentation head. Thanks for much for the architecture/code!github.com/mit-han-lab/ef…

Announcing surya - a multilingual text line detection model for documents. It gives you accurate line-level bboxes and column breaks.

Find it here - . github.com/VikParuchuri/s…
Surya was trained on a diverse set of documents, including scientific papers. It works with every language that I've tried.

It should work with good quality scanned documents as well due to image augmentation.

I'm excited to ship marker - a pdf to markdown converter that is 10x faster than nougat, more accurate outside arXiv, and has low hallucination risk. Marker is optimized for throughput, like converting LLM pretrain data.

Find it here - . github.com/VikParuchuri/m…
Nougat is an amazing model, but is slow and hallucination-prone (1.5% of pages in arXiv, 5%+ outside) due to autoregressive decoding.

Marker converts and cleans text incrementally. It uses 4 models - column detector, layout detector, nougat, postprocessor. It OCRs if needed.

1/ In this thread, I'll discuss @LambdaSchool, a bootcamp that charges 17% of your pre-tax income for up to 2 years (ISA).

tl;dr Lambda is much more expensive than the average bootcamp, and has similar outcomes. 75% of Lambda students could pay an avg of $9k less elsewhere. 2/ First, outcomes.

85.9% of Lambda graduates get a job within 180 days, with a median 60k salary.

A survey across multiple bootcamps found that 79% of all bootcamp grads were employed within 120 days, with a median 65k salary.
